Usage:

1. Find the symbolicatecrash file.

After xcode 4.3

/Applications/xcode. APP/contents/developer/platforms/iphoneos. Platform/developer/library/privateframeworks/dtdevicekit. Framework/versions/A/resources/

Before xcode 4.3

/Developer/platforms/iphoneos. Platform/developer/library/privateframeworks/dtdevicekit. Framework/versions/A/resources/symbolicatecrash

(Appendix: Display hidden files in MAC system

Enter the following command in the terminal

Command for displaying hidden Mac files: Defaults write com. Apple. Finder appleshowallfiles
-Bool true

Command for hiding Mac hidden files: Defaults write com. Apple. Finder appleshowallfiles
-Bool false

After entering the carriage return, restart the finder: The Apple icon in the upper left corner --> force exit --> finder --> restart

)

2. The symbolicatecrash file is independent of xcode and can be copied for use. The attachment is the symbolicatecrash file in xcode4.5.

3. Enter the command in the terminal. Command Format: symbolicatecrash. Crash
. Dsym>
AA. Log

That is: symbolicatecrash + crash log +. dsym file corresponding to the app +> + output file

 

4. If the message "Export _dir" is not defined

 

After xcode4.3, enter: Export export _dir =/applications/xcode. APP/contents/developer in the terminal.

 

Before xcode4.3, enter: Export export _dir =/applications/xcode. app in the terminal.

 

Suggestion: Back up the corresponding. dsym file after each version is created. After the corresponding version crashes, you can analyze the crash log based on this file.
